In today’s water systems—whether municipal, industrial, or residential—efficiency and durability are more important than ever. One of the most effective technologies for improving both is the Variable Frequency Drive (VFD). At Summit Water, we prioritize smart, energy-efficient pump systems—and VFDs play a central role in helping customers reduce costs, improve control, and extend equipment life.
Here’s how Variable Frequency Drives make a difference.
1. What Is a Variable Frequency Drive (VFD)?
A Variable Frequency Drive is a type of motor controller that regulates the speed and torque of an electric motor by varying the frequency and voltage of its power supply. For pump systems, this means a VFD can adjust pump speed based on real-time demand rather than operating at a constant speed regardless of conditions.
2. Energy Savings Through Smart Pump Control
Most traditional pump systems run at full speed and rely on throttling valves to control flow. This method wastes energy and causes wear. A VFD, on the other hand, slows the pump motor during low demand, resulting in up to 50% energy savings depending on the application.
At Summit Water, our VFD-compatible pumps are designed to:
- Match flow rates precisely to demand
- Reduce electricity costs
- Eliminate pressure surges and system shock
Over time, these savings can pay back the cost of the VFD system, making it a cost-effective upgrade.
3. Extended Pump Lifespan
By soft-starting motors and reducing frequent on/off cycling, VFDs significantly reduce mechanical stress on pumps. This leads to:
- Fewer breakdowns
- Less vibration and wear
- Longer seal and bearing life
This is especially critical in commercial and industrial systems where downtime can be costly. Summit Water offers pump packages that integrate VFDs for optimal longevity and reliability.
4. Improved System Control and Flexibility
VFDs give operators far more control over their system. With a VFD-enabled pump, you can:
- Adjust flow and pressure precisely
- Automate system responses to real-time conditions
- Integrate with remote monitoring and smart controls
Whether it’s maintaining consistent pressure in a building or adapting to fluctuating demand in a process plant, VFDs offer flexibility that traditional pump systems can’t match.
5. Reduced Maintenance and Operational Costs
Pumps operating with VFDs often require less frequent maintenance because of reduced wear on components. In addition:
- Pressure surges and water hammer are minimized
- Motors and piping experience less stress
- Fewer emergency repairs or premature replacements
This translates into lower total cost of ownership for your pumping system.
6. Pump-Specific VFD Features That Standard Motor VFDs Lack
Not all VFDs are created equal. While general-purpose motor VFDs provide speed control, pump-specific VFDs include features designed to solve the unique challenges of pumping systems. These built-in functions reduce the need for external controllers and add layers of protection that extend system life. Some of the most valuable include:
- Sleep/Wake Modes – Automatically shuts the pump off when demand drops below a setpoint and restarts when needed, reducing unnecessary run time.
- Pipe Fill and Ramp Control – Gradually ramps up pressure during startup to avoid water hammer and pipe stress.
- Multi-Pump Sequencing and Rotation – Coordinates multiple pumps without extra hardware, ensuring balanced runtime and improved redundancy.
- Sensorless Pressure and Flow Control – Uses advanced algorithms to regulate performance without requiring additional sensors, lowering installation costs.
- Dry-Run and Cavitation Protection – Detects and prevents operation under damaging conditions, safeguarding both the pump and the system.
- Automatic System Optimization – Continuously fine-tunes operation for maximum efficiency and minimal wear.
These features mean pump-specific VFDs don’t just control motor speed—they actively protect your system, improve reliability, and make operation simpler.
